The U.S. Senate overwhelmingly passed legislation aimed at strengthening the country’s nuclear energy sector, with a vote of 88-2.

Senators Ed Markey (D-Mass.) and Bernie Sanders (I-Vt.) opposed the measure. The nuclear package was combined with a bill reauthorizing the U.S. Fire Administration and firefighter grant programs, which will also go to the president’s desk.

The bill aims to accelerate the approval process for new nuclear plants and reduce licensing fees. It also mandates the Nuclear Regulatory Commission to examine ways to simplify environmental reviews. Supporters believe this measure will significantly boost the nuclear sector, with small modular reactors seen as the future of nuclear power. However, critics, like Edwin Lyman of the Union of Concerned Scientists, argue it could undermine safety by reducing regulations.

The bill passed the House in a 393-13-1 vote, with some Democrats expressing opposition.
